★TIG AC/DC：This AC/DC TIG Welder is a versatile and high-performance welding tool, designed to meet the demands of both professional fabricators and hobbyists. It seamlessly switches between AC (Alternating Current) and DC (Direct Current) modes, making it ideal for welding a wide range of metals—including aluminum, stainless steel, carbon steel, copper, and titanium.
• ★ In DC mode, it delivers stable, concentrated arcs for precise, high-strength welds on ferrous metals and non-ferrous materials like stainless steel. The AC mode, with adjustable balance control, effectively cleans aluminum oxide layers during welding, ensuring smooth, porosity-free joints on aluminum and its alloys.
• ★ Equipped with advanced features such as variable current control (10-200A), pulse welding function, and hot start capability, it offers exceptional control over weld penetration and bead appearance. The compact, lightweight design and built-in thermal overload protection enhance portability and safety, allowing reliable operation in workshops, job sites, or home garages.
• ★ Whether for thin-sheet precision welding, heavy-duty structural work, or decorative metal projects, this AC/DC TIG Welder combines durability, ease of use, and professional-grade performance to tackle any welding task with confidence.

Product Description

In TIG welding (tungsten inert gas),the welding arc is formed between a non-consumable tungsten electrode and the base material. Argon, which is most commonly used as the shielding gas, is fed through the TIG torch to shield the electrode and molten weld pool. The current is either alternating or direct current, which can be pulsed as necessary.

DC TIG WELDING

The direct-current TIG welding process is suitable for welding unalloyed and low-alloy steels, stainless steels and titanium.

AC TIG WELDING

Alternating-current TIG, and AC TIG welding is particularly suitable for welding aluminium and aluminium alloys. The primary area of application for AC TIG welding is used with materials, but the process is also used frequently in repair welding for thicker aluminium plates.
